Thermosphere contain the same gases as troposphere but in very low concentrations: oxygen, nitrogen argon.
The Aurora Borealis, also known as the Northern Lights, occurs in the thermosphere, which is the layer of the Earth's atmosphere located between the mesosphere and exosphere. It is caused by the interaction of solar particles with the gases in the thermosphere.
The density of the thermosphere is extremely low, with only a few particles per cubic centimeter. This is because the thermosphere is the outermost layer of Earth's atmosphere, where gases are highly dispersed due to the low pressure at such high altitudes.
Auroras form in the thermosphere, which is lower than the exosphere. The interaction of solar wind with Earth's magnetic field creates charged particles that collide with gases in the thermosphere, producing the beautiful light shows known as auroras.
The thermosphere is called the heterosphere because the gases in this layer are not evenly mixed. Instead, they are layered based on their molecular weight, with lighter gases like hydrogen and helium at higher altitudes and heavier gases like nitrogen and oxygen at lower altitudes. This concentration gradient results in distinct layers or regions of different composition.
The thermosphere is the layer of the atmosphere that can reach temperatures of up to 2000 degrees Celsius. This high temperature is due to the absorption of solar radiation by gases in this region. The air in the thermosphere is very thin, and high-energy solar particles contribute to the extreme heat.

The heterosphere is divided into several distinct regions based on the distribution of gases by molecular weight. These regions include the exosphere, thermosphere, and mesosphere. The exosphere is the outermost layer, containing mainly light gases like hydrogen and helium, while the thermosphere contains heavier gases like oxygen and nitrogen. The mesosphere sits below the thermosphere and holds various gases, with decreasing concentrations as altitude increases.
In the thermosphere, x-rays and gamma rays are mostly absorbed by atomic oxygen and atomic nitrogen. These high-energy photons ionize these gases, creating free electrons which contribute to the electrical conductivity of the thermosphere.
The atmospheric gases in the thermosphere are primarily heated by solar radiation. This region of the atmosphere is closest to the sun, so it receives the most intense solar energy.

The thermosphere is composed mainly of atomic oxygen and atomic nitrogen at higher altitudes, as well as ions of these elements. It is the layer of Earth's atmosphere that experiences extremely high temperatures due to absorption of solar radiation.
In the thermosphere, ultraviolet (UV) and X-ray radiation from the Sun is absorbed by the sparse gases present, leading to the ionization of these gases. This absorption process significantly increases the temperature of the thermosphere, which can reach up to 2,500 °C (4,500 °F) or higher. The ionization also contributes to the formation of the ionosphere, which plays a crucial role in radio communication and atmospheric phenomena like the auroras. However, the density of the gases is so low that the heat is not felt as it would be at lower altitudes.

The thermosphere is the layer of the atmosphere that contains the fewest gases. Although it is a very low-density layer, it is composed mainly of nitrogen and oxygen atoms.
